And so we arrived at Niagara Falls together. Dr. Wallace was kind enough to permit me to escort his charge about the Falls, and I was foolish enough to do several risky things, in a sort of half-conscious desire to appear brave--the last infirmity of the mind of a lover. I went under the Falls and clambered about in all sorts of dangerous places, in an intoxication of love. It was the same old story, only with the difference that our love was mutually discovered and confessed amid the roaring accompaniment of the great cataract. We were at the Falls forty-eight hours, and before we left we were betrothed. Soon afterward I sailed for London, as already set forth. It was not till '51 that I came back to America, principally for the purpose of marrying Miss Davis and taking her back to England with me. I arrived in Boston shortly before the celebration of Bunker Hill Day, which was always a great occasion in that city. General John S. Tyler was grand-marshal of the day, and he appointed me one of his aides. It was a time when young people were usually left out of all public business arrangements. Only the middle-aged or old took part in anything of the spectacular nature in this great parade. Probably I attracted a great deal of attention, therefore, because of my youth, being then only twenty-one. In truth, I felt a little flattered by the appointment, and determined to make as good a show as possible. Having been born and reared on a farm, I knew how to ride, so I got the stableman to give me the finest stepper he could furnish. He found a beautiful animal, with a frolicsome spirit, and I felt that I should prove at least a good part of the exhibition. I was decked in a flowing red, white, and blue sash that swept below the saddle-girths, and my horse was a proud-looking and dainty-paced beast. With a little rehearsing of my part, I was fully prepared. On the occasion of the parade, I am quite sure, I was the observed of many observers. The spectators were let into the mystery of the beautiful caracoling and dancing of my horse, whom I touched occasionally with the spur in a particular way, and who acquitted himself with great credit. The populace thought he was trying to unseat me, or to run away, and that it was only by excellent horsemanship that I was able to hold my seat and look like a centaur. I am ashamed to say, at this far distance in retrospect, that it was a proud moment for me, and that I took so much pleasure in so idle and empty a show. But youth must be served.
